BOO-F COVERING.

Application filed March 3, 1922. Serial No. 540,710.

To all whom it may concern:

Be it known that I, MAX RAoHLiN, a citizen of Russia, and resident of the city of New York, in the county of Kings and State of New York, have invented certain.

new and useful Improvements in Roof Coverings, of which the following is a specification.

The present invention relates to a roof covering, and more particularly to that type, wherein sheets of roofing material are laid and fastened to a supporting surface in the ordinary manner of laying shingles. I

In this type of roof covering, sheets of a size exceedingconsiderably that of ordinary shingles are fastened to a supporting surface on the roof, the sheets of each succeeding row overlapping the underlying row. Each of the sheets is of a width corresponding to .the length of a shingle and its length is a multiple of the" width of a shingle. The sheets are usuallyprovided each with a plurality of equidistantly spaced slots, which extend at right angles to the longitudinal center line of the sheet from one of its longitudinal edges to approximately said center line, in order to give the roof the appearan'ce of an ordinary- The main object of the present invention is to provide a roof covering of the type mentioned, wherein the exposed longitudinal edge of each sheet is held down by means carried by the underlying row of sheets, the arrangement being such that the said means engage the free edge at the slotted portion, that is to say at a place which is weakenedand thus apt to be raised even by a slight force.

With these and other objects in View, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended pended claim, without departing from the C spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention. are illustrated in the accompanying drawings, in which Figure 1' is a plan view of a portion of a roof covering, constructed in accordance with the present invention; Fig. 2 is a similar view, on a larger scale; Fig. 3 is a section taken on line 3-3 of Fig. 2; Fig. 4 is a section taken on line 4:4 of Fig. 2; Fig. 5 isa plan view of one of the fastening devices, on a larger'scale; and Fig. 6 isa view similar to the one shown in Fig. 2 of a modification of the invention. 1 Referring now first to Figs. 1 to 5, inclusive, of the drawings, the numeral 10 indicates a supporting surface on the roof construction, to which the covering is to be attached. The covering is made up of sheets 11 of any suitable roofing material, for instance of water-proof felt, that is coated with crushed slate, each sheet being of substantially oblong configuration, its length exceeding considerably that of its width. Eaclf of these sheets is provided with a plurality of eqiridistantly spaced to the longitudinal center line of the sheet the-re is fastened to the latter a row of flexible, preferably, metallic. clips 13, said clips being equidistantly spaced on the exposed surface of the sheet and located midway between the slots 12. Each clip is substantially H-shaped, the corresponding ends of the legs 14 thereof being pointed, as shown at 15, to form prongs, which are passed through the sheet-11 and then bent against the underface thereof, (Fig. 3). The distance between the legs 14 is somewhat larger than the widtli of an individual slot 12% in a sheet 11, as clearly. shown in Figs. 1 and 2 of the drawings.

The operation of this device is as follows: In laying the sheets, the same are fastened to the supporting surface and are disposed thereon in the manner of ordinary shingles. Each succeeding sheet is staggered in relation to the underlying sheet, overlapping two underlying sheets as shown in Fig. 1 of the drawings. Each sheet is secured to the supporting surface by a row of nails, denoted inthe drawings by the numeral 16, care being taken that the said nails do not penetrate the underlying sheets. After the sheets have been secured in the manner indicated to the supporting surface, the free ends of the legs 1 1 of the clips are bent over the free exposed edge of an overlying sheet, thereby holding the said exposed edge firmly in position, preventing it from being lifted by the force of wind or otherwise. r

The clips clamp down the free edges of the sheets at the slotted portions thereof, the two legs 14 of each clip engaging the overlying sheet at opposite sides of a slot, that is to say at points where the sheet is the weakest.

The slots 12 are provided in the sheets to give the roof covering the appearance of ordinary shingles. I

The modification illustrated in Fig; 6 of the drawings differs from the one above described in that the clip 13 is made of Wire, instead of sheet metal, as shown in the construction illustrated in Figs. 1 to 5, inclusive, of the drawin s. Otherwise the construction and operatlon of the elements are the same as of those described in, connection with Figs. 1 to 5, inclusive, of the drawings.

Attention is called to the fact that the covering herein described is not limited in its use to roofs, but may be employed in connection with building walls, etc.

The combination with a supporting surface, of a plurality of overlapping sheets of covering material attached thereto, each sheet being provided with a plurality of equidistantly spaced parallel slots extending from its free edge to approximately the longtudinal center line of the sheet, and a plurality of clips mounted upon the exposed face of each. sheet in a line parallel to the longitudinal center line of the sheet, each clip including two spaced legs adapted to be bent over the free edge of an overlying sheet, engaging said edge at opposite sides of a slot.

Signed at New York, in the county of New York and State of New York this 4th day of February, A. D. 1922.
